TECHNICAL FIELD

[0002] With the rapid development of new energy industry, soft package battery is widely used in electric vehicles, electric two-wheel vehicles, energy storage systems and other fields due to its good safety performance and high energy density. In soft package battery, integrated busbar is an important component of battery module, and the design of integrated busbar directly affects the overall performance, cost and production efficiency of battery module.

[0003] Currently, the integrated busbar of soft package battery module is mostly realized by plastic plus metal material or printed board plus metal material to achieve the function of series welding support. The metal material includes aluminum, copper and other metals. Although it can meet the basic strength and stability requirements, it has the following disadvantages: 1. The metal is heavy, which is not conducive to the lightweight design of the battery module; 2. The cost of aluminum, copper, nickel and other metal materials is high, which increases the overall manufacturing cost of the battery module; 3. The integrated busbar is complex to process, and hot anchor, one-piece injection molding, gluing and soldering processes are required to fixedly connect the metal and plastic support or printed board together.

[0004] In summary, the existing battery integrated busbar has the problems of heavy weight, high cost and complex processing. If the metal material design is cancelled, the heat cannot be effectively dissipated during welding, which causes the support to deform and leads to poor welding, so it cannot guarantee the reliability of welding. Therefore, there is room for improvement. UTILITY MODEL CONTENTS

The smaller opening at the other end ensures that the electrode tab forms a tighter fit with the through-slot after insertion, reducing unnecessary shaking or displacement and providing a stable foundation for subsequent welding operations. The funnel-shaped design significantly improves the speed and accuracy of electrode tab insertion, reducing assembly time and difficulty. Attached Figure Description

DETAILED DESCRIPTION

[0029] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0030] As Figures 1 to 8 shown, a battery integrated busbar, comprising: a support 100, the support 100 is set as a non-metal rigid support structure, the support 100 has at least a group of installation support units 200, the installation support unit 200 includes at least one support part 210, and the support part 210 is provided with a groove 211 at the position corresponding to the lug weld 430.

[0031] Since the lug of the electric core 400 needs to be welded on the integrated busbar, a large amount of heat will be generated in the laser welding process, so the existing integrated busbar needs to be provided with a metal piece on the basis of the plastic main body, and the metal piece is padded below the positive and negative lug bonding and welding area to enhance the structural strength of the integrated busbar, and this traditional design leads to large weight, high cost of the integrated busbar, and complex integrated busbar processing, which needs to adopt processes such as thermal anchor, integral injection molding, gluing and soldering to combine the metal and the plastic main body together.

[0032] In the present scheme, a metal piece is not needed as a welding pad material, and the whole support 100 is made of non-metallic material, for example, a plastic piece or a plastic piece is used as the support 100 to reduce the weight of the integrated busbar and reduce the cost. At the same time, the plastic support 100 has enough rigidity to support the positive and negative lug welding. Each installation support unit 200 contains at least one support part 210, and these support parts 210 are specially provided with grooves 211 at the positions corresponding to the lug weld 430. The grooves 211 help the heat generated during welding to be dissipated more effectively, avoiding the deformation of the plastic support 100 caused by high temperature of laser, in addition, this design can significantly reduce the occurrence of welding defects, such as welding spatter and false welding, at the same time, the penetration depth and welding power can be improved by about 50%. Moreover, the integrated busbar of the present scheme does not need secondary processing, and the step of installing the metal row to the support 100 is also saved, thereby improving the production efficiency and reducing the processing cost.

[0033] The bracket 100 adopts a non-metallic rigid support structure, eliminating metal parts, which greatly reduces the weight and cost of the integrated busbar, while also reducing the complexity of processing. Furthermore, a support part 210 is cleverly set on the bracket 100 for welding the positive and negative tabs of the battery cell. A groove 211 is opened on the support part 210 directly below the tab weld 430 to facilitate heat dissipation during the tab welding process, thereby avoiding deformation of the non-metallic bracket 100 during laser welding. In this way, welding quality is ensured without the use of metal parts.

[0034] Example 1:

[0035] like Figure 8 As shown, in this embodiment, the bracket 100 has only one support part 210. This design is suitable for the battery cell 400 with a double-headed tab design. In the first embodiment, each battery cell 400 is arranged end to end. The bracket 100 is designed between two adjacent battery cells 400, so the tabs of the battery cell 400 can be attached to the bracket 100.

[0036] Example 2:

[0037] like Figures 1 to 7 As shown in Embodiment 2, the mounting support unit 200 further includes at least two through slots 220. The through slots 220 are configured to allow the tabs of the battery cell 400 to pass through. The support portion 210 is configured as a solid structure between two adjacent through slots 220. Each through slot 220 and each support portion 210 are arranged alternately.

[0038] In Embodiment 2, multiple battery cells 400 can be connected in series and welded together by a bracket 100. Each mounting support unit 200 includes at least two through slots 220, which allow the battery cell 400 tabs to pass through smoothly. After passing through the through slots 220, the tabs can be bent to fit close to the support portion 210. The support portion 210 acts as a stable platform during tab welding. The support portion 210 has a groove 211 at the position corresponding to the tab weld 430. The groove 211 is designed to facilitate heat dissipation during the welding process and prevent the plastic bracket 100 from deforming due to the high temperature of the laser.

[0039] Due to the presence of the through slot 220, the tabs of the battery cell 400 can pass directly through the bracket 100 without additional positioning or adjustment steps, greatly simplifying the assembly process. The design of the through slot 220 allows the tabs to pass through the upper surface of the bracket 100, which facilitates laser welding and makes manual inspection of the solder joints easier.

[0040] Based on Embodiment 2, the through groove 220 is configured as a guide hole structure with a flared cross-section. The opening of the through groove 220 is large at the end away from the groove 211 and small at the end close to the groove 211.

[0041] The through slot 220 is designed as a guide hole structure with a trumpet-shaped cross section, which is designed to optimize the process of inserting the tab. The larger opening plays a significant role in guiding the tab, making it easier to find the correct entry, even if there is a slight positional deviation during assembly. The smaller opening ensures that the tab forms a relatively tight fit with the through slot 220 after passing through, reducing unnecessary shaking or displacement and providing a stable foundation for subsequent welding operations. The trumpet-shaped design significantly improves the speed and accuracy of tab insertion, reducing assembly time and difficulty.

[0042] Embodiment two is mainly applicable to the battery cell 400 with positive and negative tabs 410 and 420 arranged at the top. Such battery cells 400 can be stacked in sequence, and the distance between the two adjacent through slots 220 (i.e., the width of the support part 210) depends on the thickness of the battery cell 400, while the number of openings of the through slot 220 depends on the number of tabs of the battery cell 400. The opening of the through slot 220 is larger than the width and thickness of the tab, facilitating the tab to pass through the through slot 220.

[0043] When the integrated busbar of embodiment two is used for tab series welding, the two adjacent battery cells 400A and 400B are attached, the positive tab 410 of the battery cell 400A and the negative tab 420 of the battery cell 400B pass through the two adjacent through slots 220 of the mounting support unit 200, and then the positive tab 410 and the negative tab 420 are bent and tightly attached together. Then, welding is performed by a laser welding device, and the weld 430 is located directly above the groove 211.

[0044] Based on embodiment two, the bracket 100 has two groups of mounting support units 200, which are symmetrically arranged. The two symmetrically arranged through slots 220 in the two groups of mounting support units 200 are configured as a pair, and the pair of through slots 220 are arranged to allow the positive tab 410 and the negative tab 420 of the battery cell 400 to pass through, respectively.

[0045] Since the battery cell 400 has positive and negative tabs 410 and 420, the bracket 100 needs to be designed with two groups of mounting support units 200. The two symmetrically arranged through slots 220 in the two groups of mounting support units 200 are used to pass the positive and negative tabs 410 and 420 of the battery cell 400, respectively.

[0046] It should be noted that the core point of the present scheme is to replace the metal support by opening a groove 211 on the surface of the support part 210. Whether to open a through groove 220 on the support 100 depends on the specific structure and installation method of the battery cell 400. If the tab of the battery cell 400 does not need to pass through the support 100, the structure without the through groove 220 in embodiment one needs to be used, and the support 100 is only arranged between two adjacent battery cells 400. If the tab of the battery cell 400 needs to pass through the support 100, the through groove 220 needs to be arranged in embodiment two, and the through groove 220 is arranged alternately with the support part 210.

[0047] On the basis of the above-mentioned embodiments, the support 100 is provided with a positive electrode conductive row 110 and a negative electrode conductive row 120, and the positive electrode conductive row 110 and the negative electrode conductive row 120 are respectively arranged near two ends of the installation support unit 200.

[0048] The positive electrode conductive row 110 and the negative electrode conductive row 120 are respectively arranged in two positioning grooves on the support 100, and the positioning grooves are specially designed to fix the position of the conductive row, so as to ensure the stability and accuracy. The two battery cells 400 at the front and the rear of the battery cell module are respectively welded with the positive electrode conductive row 110 and the negative electrode conductive row 120, and the positive electrode conductive row 110 and the negative electrode conductive row 120 are used to be connected with the power supply and charging system.

[0049] On the basis of the above-mentioned embodiments, a sampling circuit board 300 is further included, the sampling circuit board 300 is fixedly connected with the support 100, and the sampling circuit board 300 is located between the two groups of installation support units 200. The sampling circuit board 300 is provided with a temperature sensor 310, a wire harness terminal 320 and a plurality of electric connection sheets 330.

[0050] The temperature sensor 310 is used to monitor the temperature change in the battery module in real time, which helps to prevent the occurrence of overheating and provides necessary protection mechanism. The wire harness terminal 320 allows external devices to read important parameters such as voltage and temperature of the single battery cell 400 and the whole module, and provides key data support for the battery management system (BMS).

[0051] The electric connection sheets 330 (nickel sheets) are pre-welded on the sampling circuit board 300, the number of the electric connection sheets 330 is consistent with the number of the tabs of the battery cell 400 and is arranged one by one, and then they are connected with the tabs of the battery cell 400 by using laser welding technology. This design simplifies the assembly process and ensures the quality of electrical connection. This design can make the sampling circuit board 300 electrically connected with each battery cell 400, so as to monitor the state of the battery cell 400.

[0052] As Figures 1 to 8As shown, a battery module includes a battery integrated busbar, and further includes a cell module, the cell module includes at least two cells 400 arranged in sequence, and the cell 400 is provided with a positive tab 410 and a negative tab 420; in the two adjacent cells 400, the positive tab 410 of one cell 400 and the negative tab 420 of the other cell 400 are mutually adhered and welded, and the adhering surface of the positive tab 410 and the negative tab 420 is located on the support portion 210, and the positive projection of the weld 430 of the positive tab 410 and the negative tab 420 on the support portion 210 is located in the groove 211 of the support portion 210.

[0053] The battery module can weld each cell 400 in the cell module together in series through the integrated busbar. In the two adjacent cells 400, the positive tab 410 of one cell 400 and the negative tab 420 of the other cell 400 are mutually adhered and welded together, and the adhering surface of the positive tab 410 and the negative tab 420 is located on the support portion 210, and the laser welding device performs laser welding from above the tab. The positive projection of the weld 430 of the positive tab 410 and the negative tab 420 on the support portion 210 is located in the groove 211 of the support portion 210, which means that the groove 211 of the support portion 210 is located directly below the weld 430, which facilitates heat dissipation during welding and avoids deformation of the plastic support 100 caused by high temperature laser, significantly reducing the occurrence of welding defects such as welding spatter and virtual welding. Compared with the unslotted scheme, the battery module can improve the penetration depth and welding power by 50% during series welding, solving the welding defect problem when plastic material is used as a series welding support.

[0054] In addition, the support 100 has a reasonable structure design and can stably support and fix the tabs of the soft-pack battery module, ensuring the stability and safety of the battery module during series connection. This design not only simplifies the production process, but also improves the production efficiency, as no additional aluminum or copper material needs to be installed at the bottom of the tab series welding, reducing the processing cost of the support 100. Moreover, the support 100 does not need secondary processing, and the simplified structure design eliminates the complex parts and processes of the traditional welding support 100, making the entire production process more efficient. This not only shortens the production cycle, but also reduces the production cost, improving the market competitiveness of the product.

[0055] The integrated busbar structure is reasonably designed and can stably support and fix the tabs of the soft-pack battery module, ensuring the stability and safety of the battery module during series connection. At the same time, the integrated busbar does not need secondary processing, and no aluminum or copper material needs to be installed on the support 100 at the bottom of the tab series welding, improving the production efficiency. The problem of multiple parts and complex processes of the traditional welding support 100 is solved, effectively reducing the processing cost of the support 100.

[0058] Each battery cell 400 is sequentially stacked to form a compact battery module.

In the adjacent two battery cells 400A and 400B, the positive tab 410 of the battery cell 400A and the negative tab 420 of the battery cell 400B pass out of the adjacent two through slots 220A and 220B of the installation support unit 200 respectively, and the positive tab 410 and the negative tab 420 are folded together by bending, and the abutting surface of the two is located on the support part 210 between the through slots 220A and 220B, and then the abutting surface is located on the top surface of the bracket 100, which facilitates automatic welding by the laser welding equipment. The support part 210 provides a stable welding platform for the tabs, ensuring accurate positioning and good contact during welding. The grooves 211 on the support part 210 help dissipate heat, preventing high temperatures generated during welding from damaging non-metallic materials, while improving welding penetration and joint strength.

[0059] In the embodiment three, a plurality of battery cells 400 can be welded in series by one bracket 100, that is, one battery module only needs one bracket 100, and additionally, a foam can be arranged between the adjacent two battery cells 400 as a buffer therebetween.
